Frequently Asked Questions
FAQs when downloading profiles on Beta Profiles website, hope it will be helpful to you.
Profiles on this site are developer beta profiles for iOS, iPadOS, watchOS, macOS, tvOS, and audioOS. These profiles will help you get early updates and new features but of course, will be less stable.
These profiles are created by Apple. You can check this in "Install Profile" step within the Settings app, make sure the "Signed by" line shows a green "Verified ✓". When you tap "More Detail", you will see Apple certificates.
You should ONLY install this profile when you see these credentials, other websites may fake this to trick you into installing malicious profiles.
Just checking Supported Devices page, I have listed all devices that can install profiles on this site to receive the latest updates.
Unfortunately not, deleting the profile on your device does not revert your device to an earlier software version. This simply stops your device from receiving future developer beta updates.
